报告题目：Multi-objective Evolutionary Learning: Advances in Theories and Algorithms
报告简介：
Machine learning tasks often involve multiple objective functions, which may make conventional optimization algorithms fail. Evolutionary algorithms (EAs), inspired by natural evolution, have yielded encouraging outcomes for solving multi-objective optimization problems in machine learning. However, due to the heuristic nature of EAs, most outcomes to date have been empirical and lack theoretical support. In this talk, I will introduce our efforts towards building the theoretical foundation of multi-objective evolutionary learning. First, I will introduce a general theoretical tool for analyzing multi-objective EAs. Based on this tool, I will then present the influence of recombination operators on the performance of multi-objective EAs, and the theoretical findings on how to deal with constraints and noise. Finally, I will introduce multi-objective evolutionary learning algorithms with provable approximation guarantees, inspired by the theoretical results, for two representative learning tasks, selective ensemble and subset selection.
